'''MPEG Common Encryption''' (abbreviated '''MPEG-CENC''') refers to a set of two [[Moving Picture Experts Group|MPEG]] standards governing different [[Digital container format|container formats]]:

* for [[ISO_base_media_file_format|ISOBMFF]], ''Common encryption in ISO base media file format files'' (ISO/IEC 23001-7:2016)<ref>httphttps://www.iso.org/isostandard/home/store/catalogue_tc/catalogue_detail68042.htm?csnumber=68042html</ref>

* for [[MPEG transport stream|MPEG-TS]], ''Common encryption of MPEG-2 transport streams'' (ISO/IEC 23001-9:2016)<ref>httphttps://www.iso.org/isostandard/home/store/catalogue_ics/catalogue_detail_ics70175.htm?csnumber=70175html</ref>

The specifications are compatible, so that conversion between the encrypted formats can happen without re-encryption.
